Overview of fire curtains in construction

A fire curtain is use where, if there is a fire, it is necessary to create a temporary barrier within an opening, which seals off the area on fire. The curtain descends and prevents any fire and smoke from spreading from one area to another. It also allows people access to protected escape routes without any loss of fire resistance. The paper aims to presents the results of analysis of the scientific literature on the subject of fire curtains.


Introduction
In modern scientific, regulatory, and legal and technical literature, the term "fire curtains" refers to the structure, preventing the fire from spreading through the building and its hazards (heat flow, smoke, CO, CO2, HCL et.al.).Fire curtains also known by the terms "fire-retardant curtains," "Smoke curtains", "fire and smoke curtains".Under these terms, in all their diversity we mean the curtains to prevent the spread of fire hazards.
Performing the function of a fire barrier, curtains only when necessary (in case of fire) cut off the individual volumes and escape routes of the total building space.For example, fire curtains with degree of protection EI 60, 120 or 180 do not allow the fire to spread to the neighboring room.Fire curtains are a new type of fire protection.They can be used not only in the design and construction of new buildings, but also in the reconstruction of existing buildings [1].

Results
The aim of fire protection system's usage is to maintain the temperature of the building component (structural steel element, electrical installation) bellow the critical temperature during fire but also is intended to contain a fire in the origin fire compartment for a limited period of time.In the paper [7] the passive fire protection material solutions were described

and their action mode explained.The paper [8] presents findings from comprehensive research on influence of fire barrier on fire performance of External Thermal Insulation Composite System -ETICS with combustible thermal insulation.To confirm findings, tests on identical ETICS systems were conducted in March 2014 and May 2014.
The authors [9] proposed a new way, which consists in the enclosure securable object retardant screen, in which the porous structure materials at creation environment vapor of coolant is shown a continuous physical effect of evaporative cooling.
The paper [10] describes how to use fire-screens and curtains, as part of an automatic fire protection system, in particular in the high-rise warehouse with shelves.Described in detail the action of fire barriers in case of fire in the warehouses.Table 1 provides information of fire curtains.Usually fire curtains are manufactured from a woven glass fibre fabric with stainless steel wire reinforcement.The fabric is coated on each side with silver polyurethane.The complete curtain assembly is rated at 1000 o C for a period of up to 240 minutes for Integrity (E), and 60 minutes for Irradiation (W), depending on the size of the curtain.Fire curtains are manufactured in many countries.Fire curtains are popular decision on fire safety in construction.
For Russia this is possible is a relatively new solution for fire safety [1].For example, the company Stöbich Brandschutz GmbH develops and produces fire curtains for 15 years [11].
